4 Claims.

lThis invention relates to what may be termed a log loader, the objectof the invention being the provision of a device for facilitating thetransfer of logs, in a logging mill, 'from the skid to the carriage.

A further object of the invention is to provide a device of thischaracter which is characterized by simplicity of construction,efficiency of operation, and in use will enable the rapid and easytransfer of logs incidental to the loading of the logs on a carriage orother vehicle provided for transportation thereof.

The invention together with its objects and advantages will be bestunderstood from a study of the following description taken in connectionwith the accompanying drawings wherein- Figure l is a top plan view of alog loader embodying the features of the present invention.

Figure 2 is a side elevational View of the device with the ejectormembers shown in retracted position.

Figure 3 is a View similar to Figure 2 but with the ejector members in aprojected position.

Figure 4 is a transverse sectional view through the device with certainparts omitted.

Figure 5 is a perspective view of one of the sections of the ejectormember.

Figure 6 is a perspective View of a guide member forming part of theinvention, and

Figure 7 is a perspective view of a stop head forming part of theinvention.

Referring more in detail to the drawings it will be seen that tofacilitate the transfer of logs from a skid to a carriage I provide asubstantially rectangular frame 5 to be interposed between the skid andthe carriage for transferring the logs from the skid, individually, tothe carriage.

The 'frame 5 has opposite side or longitudinal members li provided atone end thereof with arcuate recesses forming transversely aligned seatsfor the 'log to be forced from the frame 5 onto the carriage. i

At the seat-equipped ends 1 thereof, the members 6 of the frame arereinforced through the medium of metallic plates 8, the plates 8 havingarcuate intermediate portions which form liners for the seats l.

Intermediate the ends of the side members 6 of the frame, there arebolted or otherwise secured to the undersides of such members bearings 99.

Rotatably supported through the medium of the bearings 9 is a shaft 'I0that intermediate its ends is provided with a crank I I.

The crank II is adapted to be connected through the medium of a link I2with any suitable mechanism for rocking the shaft Il! to project andretract the log-ejecting elements I3.

There are two log-ejecting elements I3, one disposed at each side of theframe 5.

Each ejector I3 embodies a section I4 that has a sliding workingtthrough a substantially channel-shaped guide I5 bolted or otherwisesecured, as at I5, diagonally to an adjacent side member 6 at the outerside of the frame.

To facilitate movement of the section i4 of the ejector through theguide I5 the latter is provided with a suitable roller Il upon which themember I 4 rests.

Each ejector member I 3 also embodies a section I'8 that has a slidingworking t in an elongated guide member I5 secured laterally to thesection I4.

At the respective opposite ends thereof the shaft I0 is provided witharms 2l) to which are pivoted, as at 2|, the ejector sections I8.

Each ejector section I 3 has disposed thereabout a coil spring 22that atone end impinges against the associated guide I9 and at an opposite endimpinges against the shoulders 23 provided adjacent the pivoted end ofthe section or member I8 of the ejector.

At the extremity thereof remote from the pivot 2l the member I8 of theejector has secured thereto, through the medium of a screw or suitablefastening element 24, a substantially U- shaped stop cap 25 that engagesthe guide I9 in a manner to limit movement of the section I8 in responseto the action of the spring 22 relative to the section I4 of theejector.

Also movement of the ejectors I3 to a retracted position is limitedthrough the medium of stop extensions 26 provided on the free ends ofthe sections I4 of the ejectors I3 as shown.

In actual practice the log to be transferred from the skid to thecarriage is moved from the skid onto the 4frame 6 to settle in the seats1 with the ejectors I3 in the retracted position shown in Figure 2` Whenthe seating of the log has been accomplished, shaft I0 is rocked tocause the ejectors I3 to move longitudinally through the guides I5 thusbringing the forward or free ends of the members or sections I4 of theejectors into engagement with the log in a manner to unseat the log andforce the same from off of the frame 5 onto the carriage.

Thus it will be seen that'with a device of this character the transferof logs onto the carriage can be quickly and easily accomplished.

While I have herein illustrated and described what is considered thepreferred embodiment of the invention, I am well aware that in actualpractice minor changes may be resorted to either from expediency ordesire. Consequently I do not wish to limit myself to the precisedetails herein illustrated and described, but claim all such forms ofthe invention to which I am entitled.

I-Iaving thus described the invention what is claimed as new is:

1. In a log handling device, a frame provided adjacent one end thereofwith means to accommodate a log in a relatively stationary position onthe frame, ejector members slidably mounted on the frame 4at oppositesides thereof and movable to a projected position for engaging the logand displacing it from its seated position on the frame, a crank foreach ejector member, an operating connection between said ejectormembers for simultaneously projecting and retracting such members, andspring means between each crank and its associated ejector member placedunder tension upon initial ejecting movement of the members, and adaptedto subject the log to the force of the spring means for continuing theejecting movement of the members after the completion of the throw ofthe crank.

2. In a log handling device, a frame provided adjacent one end thereofwith means to accommodate a log in a relatively stationary position onthe frame, ejector members slidably mounted on the frame at oppositesides thereof and movable to a projected position for engaging the logand displacing it from its seated position on the frame, a crank foreach ejector member, an operating connection between said ejectormembers for simultaneously projecting and retracting such members, eachof said ejector members including a pair of sections one of which isprovided with a guide, and the other of which has a working fit in saidguide, spring means between each crank and its associated ejector memberplaced under tension upon initial ejecting movement of the members, andadapted to subject the log to the force of the spring means forcontinuing the ejecting movement of the members after the completion ofthe throw of the crank, and stop means on one of the sections cooperablewith said guide for limiting such relative movement of the sections inresponse to said spring.

3. In a `device for facilitating the transfer of logs from a skid to acarriage, a frame adapted to receive the logs from the skid incidentalto transferring the logs to the carriage, said frame having side membersprovided adjacent one end of the frame with arcuate recesses formingseats for the logs, guides mounted on the side members of the frameadjacent said seats, ejectors working through said guides and includingslidably connected sections, a shaft rotatably mounted transversely ofthe frame, cranks on said shaft, pivotal connections between said cranksand said ejectors for transmitting movement of the shaft to theejectors, spring means between thesections of the ejectors placed undertension upon initial ejecting movement ,of the ejectors and adapted tosubject the log to the force of the spring means for continuing theejecting movement of the ejectors after completion of the throw of thecrank and means for rotating said shaft.
